ICD-10: T61.03

Ciguatera fish poisoning (CFP) is a foodborne illness caused by the consumption of fish contaminated with toxins produced by marine dinoflagellates, primarily Gambierdiscus toxicus. This condition is particularly associated with reef fish found in tropical and subtropical waters. The clinical presentation and details surrounding the diagnosis and coding of ciguatera fish poisoning, specifically under ICD-10 code T61.03, are essential for accurate medical documentation and billing.

Clinical Description of Ciguatera Fish Poisoning

Etiology

Ciguatera fish poisoning occurs when individuals consume fish that have accumulated ciguatoxins through their diet, primarily from algae that are ingested by smaller fish, which are then eaten by larger predatory fish. Common fish species associated with CFP include barracuda, grouper, snapper, and amberjack.

Symptoms

The symptoms of ciguatera fish poisoning can vary widely and may include:

• Gastrointestinal Symptoms: Nausea, vomiting, diarrhea, and abdominal pain typically occur within a few hours to a few days after consumption of contaminated fish.
• Neurological Symptoms: Patients may experience tingling or numbness in the extremities, muscle weakness, and in some cases, temperature reversal (where hot feels cold and vice versa).
• Cardiovascular Symptoms: Bradycardia (slow heart rate) and hypotension (low blood pressure) can also occur, leading to more severe complications in some cases.

Diagnosis

Diagnosis of ciguatera fish poisoning is primarily clinical, based on the history of fish consumption and the presentation of symptoms. Laboratory tests are not routinely used for diagnosis but may be employed to rule out other conditions.
